Isolation of Mouse Embryonic Neural Stem Cells and Characterization of Neural Stem Markers by Flow Cytometry.

Neurogenesis is outlined as a process in which new neurons are generated from neural stem cells (NSCs). This process comprises proliferation and fate specification of NSCs, migration of newborn neurons, and their maturation. Defects in embryonic neurogenesis have emerged as a key mechanism underlying neurodevelopmental disorders such as autism spectrum disorders and intellectual disability. An impairment in neurogenesis has also been observed in neurodegenerative disorders such as Huntington's disease. Transgenic animal models of neurodevelopmental and neurodegenerative diseases have been developed which serve as invaluable tools to investigate the early mechanisms of disease pathogenesis. In this chapter, we describe our optimized method to obtain and maintain reproducible neurosphere cultures from transgenic or patient mouse models followed by characterization of NSCs by flow cytometry.
